You wouldn't think it would be that hard to find out for sure what harness I need to connect the 300di to my car... how wrong I were. I emailed a company (Car Communications Ltd) who supply and fit these units and to say they don't want to tell me is an understatement, I asked if the sot-963 was the correct lead and they said no, didn't offer any advice on which one I needed to buy from them, but said I could do it with the right aerial connectors and aux lead??? I emailed them back and said the unit had to be powered and that an aux and aerial wires wouldn't do that, again asking which harness I needed... no reply.. Emailed them prior to that and they just linked me back to their order page which shows no options for harness.
From what I have researched there are only 4 wires from the 300di power loom required, perm live, switched, ground and cabin illumination. So apparently you can remove the connector at the end on the power loom and connect directly with the relevant wires on the car audio loom or straight to the fuse box. The other wires are not required.
